The Room of Requirement is one of the many mysterious places in Hogwarts Castle.

It is said that this room will only appear when one really needs it.

Neville Longbottom discovered it by chance, and Harry Potter used this secret room as a base for D.A. meetings.

At the same time, they can also conduct secret magical training here.

I have to say that even if Harry can't be the head of the Aurors in the future, he will be a competent teacher.

Patient, meticulous, and relatable.

Of course, if Harry's face hadn't been so red when he was teaching Zhang Qiu to use the Disarming Charm, it would have made the young teacher look even more selfless and great.

At every meeting in the Room of Requirement, Harry would teach the D.A. members about the defenses against the dark arts.

In addition, Harry will also contribute his spell-casting techniques and experience without reservation.

Therefore, the members of the D.A. Legion were quickly impressed by Harry's character, and even in the face of Umbridge's intimidation threats, none of them chose to betray Harry.

Gryffindor's common room.

"No, I don't agree with you doing that." There was a hint of displeasure on Hermione's pretty face.

As the words fell, Miss Know-It-All closed the magic book she was holding in her hand.

"Don't worry, it's just a Boggart, we'll be able to deal with it by the time we're in third grade, won't we? Harry. ”

Ron looked at his surroundings weakly, and after confirming that there were only three of them in the common room at this time, he still whispered.

"We do need the Boggart to practice the Patronus Charm, it will make the environment in which we practice in the Room of Requirement a little more realistic, but I think we should let everyone know beforehand."

Harry sat on the warm blanket on the floor, and he objected to Ron's proposal.

"Don't you want to see what he fears the most?" Ron said with an encouraging smile, continuing to encourage the two companions beside him.

That exchange student with a mysterious origin always looks so perfect.

He also needed a little practice to cast most of the spells with a wave of his wand.

Even the Dark Lord, who had made the entire wizarding world so distracted that he didn't even dare to mention his name, seemed to them that Lu Li was sure that he would be able to face it calmly.

Harry stared at the flames burning in the closet and remained silent, knowing that he had been persuaded by himself.

It's just a little prank.

Seriously, Harry would have liked to see what Lu Li feared the most.

"Okay, but just once." Hermione exhaled slightly.

Well, she also compromised.

When he invited Lu Li to join D.A., he said that the proud organization was a children's club.

Hermione's heart was angry, and even now that she thought about it, she was still angry.

Imagining Lu Li's panicked expression in his mind, a hint of revenge flashed in the heart of this know-it-all lady.

This should be one of the reasons why she would agree to Ron's prank.

……

On Saturday afternoon, it was the day when the D.A. Army reassembled.

Inside the Responsive Room, Harry was standing in front of the crowd, patiently explaining the gist of a certain high-level spell.

The main lesson of this assembly was the Patronus Charm that Harry taught everyone.

"The spell that summons the Patronus Charm: Call the God Guard, everyone should already know this."

"When casting a spell, we must concentrate and think about what is happiest in our hearts."

"Embodied Patronus is often hard to produce, but when facing opponents, Shield mode works just as well."

Sentence after sentence, Harry explained the main points of the spell in a coherent manner.

As he spoke, he flicked his wand again, and a silvery-white light like moonlight burst out from the tip of his wand.

As Harry channeled more magic with his wand, the silvery-white light eventually erupted, converging and condensing into the shape of a handsome stag with a semi-transparent shadow.

Being able to cast a Patronus Charm with a form is enough to show that Harry has a very high talent when it comes to the defense of the dark arts.

Of course, higher-level Patronus can not only defend against Dementor attacks, but also transmit messages by speaking.

However, the High Patronus can only be cast by a few wizards with high mana.

Even Harry now has a hard time doing that.

Fortunately, Harry was still very young, and the average Hogwarts fifth-year student had never even heard of the Patronus Charm, let alone cast a Patronus Charm with a form as skillfully as he did.

Also, according to the grapevine, the high-ranking Patronus was still made by Dumbledore, the old headmaster.

"Call the gods to protect you."

The spell sounds simple, but it's not easy to cast successfully.

The Patronus advocates a happy time and the hope of living, and the Patronus requires a strong magical foundation, much higher than the level of ordinary wizards.

Each patronus is unique because each person's personality and inner world are different, and the emotions expressed are also different.

So on this spell, Harry could only provide a general direction, as well as piggyback on some of his own experience.

"Let's give it a try, and remember, the key is to concentrate on what is happiest in your heart while reciting the mantra."

Harry waved his wand again, and the half-transparent stag stomped its feet lightly in midair, and then turned into a few rays of silver-white light and quietly disappeared into the room of requirement.

After seeing Harry's cool patronus in form, many young wizards were moved and couldn't wait to start trying to wave their wands.

It's just that this is the first time to wave a wand, and there are very few people who can cause magic effects, let alone successfully cast this spell.

"Try it too, my friend."

Harry came to Lu Li's side, smiling and motioning for him to try the new spell as well.

"Call the gods to protect you."

Lu Li said the spell accurately and clearly, and at the same time waved the wand in his hand.

A striking silver-white glow was fleeting at the tip of the wand in his hand.

In the room, many people's attention was attracted by this certain light.

"The shaking of the wrist is even smaller." Harry pushed the round-framed eyes on the bridge of his nose and gave his advice at the right time.
